Data from: Between-year changes in community composition shape species' roles in an Arctic plant-pollinator network
Inter-annual turnover in community composition can affect the richness and functioning of ecological communities. If incoming and outgoing species do not interact with the same partners, ecological functions such as pollination may be disrupted. Here, we explore the extent to which turnover affects species' roles --as defined based on their participation in different motifs positions-- in a series of temporally replicated plant-pollinator networks from high-Arctic Zackenberg, Greenland. We observed substantial turnover in the plant and pollinator assemblages, combined with significant variation in species' roles between networks. Variation in the roles of plants and pollinators tended to increase with the amount of community turnover, although a negative interaction between turnover in the plant and pollinator assemblages complicated this trend for the roles of pollinators. This suggests that increasing turnover in the future will result in changes to the roles of plants and likely those of pollinators. These changing roles may in turn affect the functioning or stability of this pollination network.
Flower color and flowering phenology mediate plant-pollinator interaction assembly in a diverse co-flowering community
<p>Uncovering the role of competition and facilitation in community assembly is central for developing a predictive understanding of the forces that organize biodiversity. Standard trait-based approaches however rely on detection of only one assembly mechanism (competition or facilitation) along a single trait even though pollinator-mediated plant-plant interactions can be structured along multiple phenotypic, phenological and ecological traits. We evaluated plant species distribution along multiple phenotypic and ecological traits (flower color, flowering time, pollinator sharing) and described an entire co-flowering community as a set of modules with unique patterns of assembly, to test predictions regarding the relative contribution of competition and facilitation to the assembly of a diverse co-flowering community. We show a modular pattern of flower color assembly. Flower color modules differ in their spectral reflectance patterns including color hue and saturation. Within modules, however, species are differentially assembled along phenological and ecological traits (pollinator sharing) depending on the main pollinator group visiting plant species within each module. Results suggest different trait assembly patterns within individual trait-modules in the same co-flowering community and that different trait-patterns can result from the same type of ecological interaction. This study reveals empirical evidence of community assembly along multiple axes of trait differentiation and raises caution when interpreting assembly patterns based on a single trait.</p>

Biotic and abiotic drivers of plant-pollinator community assembly across wildfire gradients
<p>1. Understanding how abiotic disturbance and biotic interactions determine pollinator and flowering-plant diversity is critically important given global climate change and widespread pollinator declines. To predict responses of pollinators and flowering-plant communities to changes in wildfire disturbance, a mechanistic understanding of how these two trophic levels respond to wildfire severity is needed.</p> <p>2. We compared site-to-site variation in community composition (β-diversity), species richness, and abundances of pollinators and flowering plants among landscapes with no recent wildfire (unburned), mixed-severity wildfire, and high-severity wildfire in three sites across the Northern Rockies Ecoregion, USA. We used variation partitioning to assess the relative contributions of wildfire, other abiotic variables (climate, soils, topography), and biotic associations among plant and pollinator composition to community assembly of both trophic levels.</p> <p>3. Wildfire disturbance generally increased species richness and total abundance, but decreased β-diversity, of both pollinators and flowering plants. However, reductions in β-diversity from wildfire appeared to result from increased abundances following fires, resulting in higher local species richness of pollinators and flowers in burned than unburned landscapes. After accounting for differences in abundance, standardized effect sizes of β-diversity were higher in burned than unburned landscapes, suggesting that wildfire enhances non-random assortment of pollinator and flowering-plant species among local communities.</p> <p>4. Wildfire disturbance mediated the relative importance of mutualistic associations to β-diversity of pollinators and flowering plants. The influence of pollinator β-diversity on flowering-plant β-diversity increased with wildfire severity, whereas the influence of flowering-plant β-diversity on pollinator β-diversity was greater in mixed-severity than high-severity wildfire or unburned landscapes. Moreover, biotic associations among pollinator and plant species explained substantial variation in β-diversity of both trophic levels beyond what could be explained by wildfire and all other abiotic and spatial factors combined.</p> <p>5. Synthesis: Wildfire disturbance and plant-pollinator interactions both strongly influence the assembly of pollinator and flowering-plant communities at local and regional scales. However, biotic interactions were generally more important drivers of community assembly in disturbed than undisturbed landscapes. As wildfire regimes continue to change globally, predicting its effects on biodiversity will require a deeper understanding of the ecological processes that mediate biotic interactions among linked trophic levels.</p>
Data from: Constructing more informative plant-pollinator networks: visitation and pollen deposition networks in a heathland plant community
Interaction networks are widely used as tools to understand plant–pollinator communities, and to examine potential threats to plant diversity and food security if the ecosystem service provided by pollinating animals declines. However, most networks to date are based on recording visits to flowers, rather than recording clearly defined effective pollination events. Here we provide the first networks that explicitly incorporate measures of pollinator effectiveness (PE) from pollen deposition on stigmas per visit, and pollinator importance (PI) as the product of PE and visit frequency. These more informative networks, here produced for a low diversity heathland habitat, reveal that plant–pollinator interactions are more specialized than shown in most previous studies. At the studied site, the specialization index Embedded Image was lower for the visitation network than the PE network, which was in turn lower than Embedded Image for the PI network. Our study shows that collecting PE data is feasible for community-level studies in low diversity communities and that including information about PE can change the structure of interaction networks. This could have important consequences for our understanding of threats to pollination systems.
Data from: Influence of plant-pollinator interactions on the assembly of plant and hummingbird communities
Understanding how ecological processes structure species assemblages is a central issue in community ecology. While the influence of plant–pollinator interactions on each other's evolution is well recognized, their role in the assembly of interdependent communities of plants and pollinators is still unclear. Using data from seven communities of hummingbirds and plants that they pollinate from two tropical rain forest types (lowland and montane), we evaluated phylogenetic relationships and signal of functional traits, over space and time, to test predictions on the main processes (environmental filtering, facilitation or competition) that are driving these hummingbird–plant assemblages. Our findings suggest that the main processes driving these assemblages varied between hummingbirds and plants and between habitats, and even among communities at the same habitat. The non-conserved floral trait and the phylogenetic patterns (even or random) give support to the hypothesis of facilitation or competition as processes regulating the composition of plant assemblages. Moreover, the positive relationship between fitness and flowering synchrony suggests facilitation as the most important mechanism for montane plant communities. Distinctively, for lowland plant communities, the combination of non-conserved traits and clustered phylogenetic patterns may be a result of either adaptive radiation or biotic filtering driven by a particular pollinator species that plays a main role as plant community organizer. Lastly, evidence of trait conservatism, together with clustered or even phylogenetic patterns, suggests that facilitation or competition may drive the assembly of montane hummingbird communities, despite the predominance of random phylogenetic patterns. Synthesis. Overall, we present a pathway to identify central ecological processes that may drive the assembly of plant–pollinator communities. We show that different processes related with pollination that vary in space and time may contribute to the assembly of the interdependent tropical communities of plants and pollinators. These findings highlight the importance of considering ecological interactions when evaluating community assembly processes.
